Description

Heel setting part for pressure distribution of insole in a shoe for women, insole having the same and shoe for women havig the insole}

The present invention relates to a shoe midsole, and more particularly, to a midsole of the midsole having a structure capable of dispersing the pressure applied to the sole in a heeled women's shoes and a midsole and shoes employing the same.

The foot is an elaborate and delicate organ composed of many bones, joints, ligaments and numerous muscles and tendons. These foot components form a basic fixed structure to perform the function of the foot well in the line state and the moving state, and forms a few formal shapes and structures by the combination of each other in each state.

Shoes can play a positive role in protecting these feet from damage from external heat, cold, and contact with external objects, and alleviating the impact on the feet when moving. However, shoes, on the other hand, may adversely affect the foot by limiting natural foot movement.

For example, women's dress shoes with a high heel of 5 cm or more, that is, high heels, the first step of walking rather than a natural four-step walking, based on the shape of the walking foot. That is, when walking, the shape of the foot is fixed by the shape of the high heels itself in the form of a magpie foot similar to the type 2 plantar flexion that always holds the heel. In addition, the high heels are pushed to the forefoot in four stages while the second type plantar flexion continues without the first type plantar flexion. Therefore, when walking high heels, the elasticity of the muscles due to the deformation of the foot muscles are not fully utilized, and the plantar flexion function in the pushing motion of the toes is significantly reduced.

In addition, the high heels have a forefoot with a sole that touches the ground even when the user moves or stops, and a rear foot (heel) spaced a certain distance from the ground by a high heel, so that the inclination of the bottom of the shoe is inevitable, Due to the inclination of the portion connecting the forefoot and the forefoot, the forefoot of the foot is not stable on the shoe and is always forced to the front of the shoe along the inclination of the inner surface of the shoe. By this force, the user's weight is concentrated on the heel, and the narrow cheeks in front of the shoe are likely to cause hallux valgus.

On the other hand, ordinary shoes have a midsole on the sole, and the periphery of the upper is fitted and fixed between the sole and the midsole along the periphery. Inside the periphery where the upper is fitted, a sponge layer is installed to remove the step instead of the upper and to adhere the sole to the midsole.

The midsole of a shoe, such as high heels, is a zip that is attached to the front of the sole and to the bottom of the tack and the latter half of the tack (from the end of the foot to the heel of the foot, ie the sole where the sole touches the ground). It is provided. The band is usually made of paper or pulp material, and the ivory band and the bottom band are overlapped in plural layers. The band is thicker and harder than the tack and forms a certain shape. Between the folds and the folds that make up the band, there is a waistband, also called shank, in the longitudinal direction, which serves as a support frame. The thrust is installed on the inclined portion connecting these portions between the heel and the heel of the shoe, and pressure is applied to the portion by the user's weight or the user's movement to prevent the inclined portion of the shoe window from collapsing or falling. That is, the waistband plays a very important role such as the spine of the human body to maintain the inclined shape of the shoe sole.

However, the normal midsole simply serves to fix the upper, and to cover the upper periphery attached to the sole of the shoe when viewed from the inside of the shoe, it was difficult to make the foot particularly comfortable or to have a function that suits the characteristics of the user. . In this state, the top of the sole of the high heels is finished with a thin layer of cover called 'carre', so that the upper surface of the midsole is the same as the upper surface of the shoe that the user's sole touches. This is a structure that is not comfortable to give functionality, such as many functional sneakers developed in recent years, especially in the case of high heels has become a factor that makes it difficult to give a functional enough to cover the structure that gives a burden to the user's feet.

The present invention is to solve or alleviate the problems of the conventional high heel shoes described above, more specifically, in the high heel shoes to reduce the phenomenon of the back squeezing of the foot to the front of the configuration by distributing the pressure applied to the sole to ease the foot The purpose is to provide.

The object of the present invention is to provide a functional form to the midsole of the high heel shoe to distribute the pressure of the sole compared to the simple flat midsole to provide shoes and parts that can pursue the stability and comfort of the foot.

Women's shoe midsole of the present invention for achieving the above object is made to cover the corresponding area of the second half of the foot while maintaining the form without being easily deformed by external force,

When a line extending in the longitudinal direction of the foot along the upper surface of the arm is called a shape line S, the shape line has a portion protruding upwardly from a straight line obtained by connecting both ends of the length direction of the arm. In this straight line, the length of the line that is perpendicular to the straight line meets the shape line is called the separation distance between the straight line and the shape line. ), The maximum separation point (X) exists at the front (heel side) of the straight line at the half point (M) of this straight line and before the point (M ') that meets the shape line.

In addition, the ratio of the separation distance divided by the length of the straight line in the present invention can be referred to as the separation distance ratio, when the most spaced point in the straight line of the convex portion is the maximum separation point, the length of the straight line connecting both ends and The ratio of the maximum separation distance D1, which is the maximum value of the separation distances from the straight line to the shape line, is the shape of the inner shape line S1 based on the inside of the foot in more detail and the outer shape based on the outside of the foot. When divided according to the width direction position of the foot, such as the line (S2), it can be 8% to 20% in the inner shape line (S1), 4% to 17% in the outer shape line (S2).

The band of the present invention is in front of the heel portion and the heel portion where the upper surface forms a slight inclination of 15 ° or less with the ground (horizontal surface) as a whole when viewed from the side with the midsole applied to the shoe. It may be provided with an inclined portion that is unfolded and has a difference of 30 ° or more from the slope of the heel portion and a slope, and a connection portion constituting a curved surface connecting the heel portion and the slope portion to form a steep slope of 45 ° or more. The heel corresponding part generally means from the rear end of the foot to just below the part called the astragalus, but here it means a part including at least 2/3 or more of the horizontal length from the rear end of the foot to the lower part of the astragalus. The connecting portion preferably has a horizontal length of 40% or less than that of the heel portion, and the front of the inclined portion usually has a convex downward portion for natural connection with the ground (horizontal surface).

The band of the present invention can be made in the form of holding the waist (shank portion) in the frame made by overlapping the material, such as the paper as in the prior art, made of a solid synthetic resin, while forming an integral shank portion thicker than the surrounding It can be made with. In this case, the synthetic resin band may be formed through a synthetic resin molding process such as injection molding.

In the present invention, the shank portion may be formed by protruding the bottom of the sub-band, and extends in the longitudinal direction for a supporting action as a function of the shank portion.

Women's shoe midsole of the present invention is provided to cover the front of the foot in the state in which the combination of the band and the tactile is provided with a traction attached to at least a portion of the bolus of the present invention and the bottom of the present.

In the women's shoe midsole of the present invention, the bottom of the band may be provided integrally with the shank portion protruding downward from the bottom of the band in the longitudinal direction of the foot. In this case, the traction may have a perforated portion corresponding to the shank portion so that it does not have a step at the bottom of the midsole when it is coupled to the bottom of the abutment, or has a relaxed step compared to the height of protrusion from the bottom of the shank portion.

The women's shoe of the present invention is a women's shoe having a sole and a midsole including a heel of 5 cm or more as a flooring material, characterized in that it comprises a women's shoe midsole of the present invention.

In the women's shoes of the present invention, in the area where the midsole is formed solely of the tack, the upper part and the tack overlap the upper part and the tack using a fastener that penetrates, and the upper part of the lap overlaps with the tack. Can be formed.

According to the present invention, the heel portion is horizontally placed by varying the inclination of the bottom portion of the shoe that connects the part touching the ground from the rear end spaced apart from the ground in the women's shoe so that the heel and the big toe part are weighted. By dividing the pressure caused by the weight into the heel can be effectively reduced.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view showing a midsole according to an embodiment of the present invention, Figure 2 is a bottom view of the band according to an embodiment of the present invention, Figure 3 is a plan view of the band according to an embodiment of the present invention.

In Fig. 1, the lower layer is a tack 20 corresponding to the entire foot surface, and is generally made of paper and thinner than the band. In FIG. 1, the band 10 is provided only in an area corresponding to the latter half of the entire foot surface above the traction 20. The band 10 is formed thicker than the tack 20, and is made of a hard synthetic resin, that is, hard synthetic resin that is not easily deformed by an external force.

In this embodiment, there is no shank constituting a separate member, and the band 10 has an integral shank portion 11 that protrudes downward on the bottom and extends in the longitudinal direction. The synthetic resin material band is formed through a synthetic resin molding process, and in particular, may be formed by an injection molding method in which a molten thermoplastic plastic is pressed into a mold (mold) to fill a mold. In this case, the subband, in which the shank portion and the peripheral portion except the same, are integrated, may be formed in one mold. Therefore, once the mold is manufactured, it does not incur a separate processing cost for forming the shank portion, thereby saving time, cost and effort in the production of shoes, that is, the midsole.

FIG. 4 is a side view viewed from the inner side (middle point of the two feet of the shoe wearer) while the belt is applied to the midsole according to an embodiment of the present invention and is mounted on the shoe, and FIG. 5 is the band 10 in FIG. The inner contour line (the uppermost line corresponding to the upper inner surface of the lower arm: S1) is represented by the contour line (S) of the shoe in accordance with the change in the length from the rear end compared to the inner contour line of the lower arm (S ') of the conventionally designed women's shoes. This graph shows the change in height.

The inner shape line S1 of the inventive design has an upper surface in the longitudinal direction of the ground (horizontal surface) of 15 ° or less, more specifically, a tangent at each point in a range of 10 ° to 15 °, and a total of about 11 °. The heels corresponding part A, which forms a gentle inclination, runs near the straight line by a distance (half of the horizontal length of the whole band in horizontal length) from the rear end of the band.

Next, the heel corresponding to the heel when the connecting portion (C) in which the tangential slope at each point is in the range of 15 ° to 50 °, and the straight line connecting the two end points has a slope of about 35 ° as a whole, is viewed as a horizontal length. It is 35% of the length of (A).

Following the connection part C, the inclination part B which is almost straight ahead along the longitudinal direction of a foot is located. The inclined portion B has a shape line length of inclined state of about 65% of the heel portion, and the inclined portion is 52 degrees to 53 degrees. In front of the inclination portion (B) may have a convex portion (E) convex downward for a natural connection with the ground (horizontal surface).

The inner shape line S1 of the upper surface extending in the longitudinal direction has a convex portion upward from this straight line when connecting the both ends of the longitudinal direction in a straight line, and the most spaced apart point is the most spaced apart from the upper straight line among the convex portions. In this case, the ratio of the length of the straight line connecting both ends and the maximum separation distance D1, which is the maximum value between the straight line and the contour line, is effective from 8% or more in the inner contour line S1 of the foot. It is advantageous to have a more obvious effect from 10% or more, preferably to 12% or more. However, in a wearable structure, it is difficult to exceed a certain value, for example, 20%, and in this embodiment, it is about 15%. In the outer shape line (S2) of the foot, the maximum separation distance ratio is preferably in the range of 4 to 17%. If this ratio is low, the upper surface of the sub-bow is too far from the arch shape of the foot, and thus has an inclination close to a straight line as in the prior art, so that the effect of dispersing pressure on the sole is low. As shown in the figure, the steep slope is formed, and in the severe case, pressure is applied to the center portion of the arch, thereby increasing discomfort.

At this time, since the inside of the bottom of the foot is formed more distinctly than the outside for the same subband, the medial shape line as shown in FIG. The change of the separation distance ratio in S1 is larger than the change in the separation distance ratio in the outer shape line S2, and the maximum separation distance ratio of the inner shape line S1 is also the outer shape line S2 in terms of the maximum separation distance ratio. ), The maximum separation distance ratio of 3% point (% point means the difference between the% value, for example, 8% -5% = 3% point) to 5% point is preferable.

Also, when the straight line is referred to, the maximum separation point X of the shape line S1 is drawn perpendicularly to the straight line at the half point M of this straight line, and is later than the point where the shape line S1 meets the shape line S1 (the heel side). Present in)

For reference, the shape line S 'drawn by the normal inner side of the upper side of a conventional high heels with respect to the inner side of the upper side of the sub-shape is a form in which the heel portion and the inclined portion of the present invention are close to a straight line. In contrast, the ratio is generally close to a gentle curve, and above all, when connecting both ends in a straight line, the ratio of the length of the straight line connecting both ends and the maximum separation distance (D ₂ ) of the shape line (S ') from the straight line is 8 Less than%. In addition, the maximum separation point X 'based on this straight line is located at or substantially behind the point that is drawn vertically at the half point of the straight line.

When comparing the present embodiment with the lower band of the conventional high heel midsole, the upper medial upper contour of the middle band of the midsole is more clearly defined as the inner side of the foot than the outer side of the foot with the calf, and the weight is applied according to the slope of the curve. This is because the difference is more clearly than the outside.

In the present invention, the inclined state of the inner upper surface of the band may have a slight difference in stability depending on the material of the cover over the midsole. It can be seen that the heel is responsible for most of the weight on the heel, and the pressure on the heel is reduced compared to the prior art.

In the shape line of the present invention, the connecting portion preferably has a length of 40% or less based on the horizontal length compared to the corresponding heel portion, and when the connecting portion is long and the radius of curvature is large, the inclined portion and the corresponding heel portion are more naturally connected. Although it may have a shape, the slope of the inclined portion is larger, so that the foot is bent excessively at the ground portion, so it should have a length of 40% or less. On the other hand, if the length of the connecting portion is small, the radius of curvature of the connecting portion is small to match the difference in the inclination angle of the heel corresponding portion and the inclined portion. Therefore, determining the upper limit of the connection length and the lower limit of the radius of curvature may have the effect of limiting the shape and characteristics of the band, such as defining the upper limit and the lower limit of the connection length. The specific curvature of the joint may be different depending on the height of the heel and the length of the foot, but if the curvature of the joint is too small, the purpose of the design can be achieved, but the weight of the heel is concentrated near the joint. Since the sole of the part is easily damaged by the intensive pressure of the foot, the radius of curvature is formed to 5 to 15 cm, but preferably the most urgently bent radius of curvature is 10 cm or more.

The upper surface of the band in the embodiment of the present invention may be made of a smooth surface of a smooth curve, such as the surface of the sole, but may be provided with a functional part having a partially protruding or partially elastic. Therefore, the upper surface is not usually flat even in the left and right width directions. For example, the shape of the foot is concave so as to accommodate the shape of the foot in the heel. In addition, the sole of the shoe has a constant thickness, and compensates for the curved surface of the sole of the foot, which is not satisfied through the shape of the sole, for example, the inner surface of the foot, to increase the natural contact with the sole to increase the weight distribution effect. The thickness of the band may be formed slightly thicker than the outside on the inside.

In addition, the band of the present invention is difficult to give a sufficient thickness and shape change due to the limitation of the structure formed by laminating paper in the conventional paper band, but it is easy to form integrally by synthetic resin molding or injection molding. It may be easier to impart various forms depending on the purpose for correcting the pathology. For example, a slight convex portion of the inclined portion of the upper surface of the upper abdomen (12 in Fig. 3) is formed thickly so that the foot compensates for the curved surface along the side arch, or gives acupressure effect to the muscles of the foot. , Screw holes (13 in Figure 3) for coupling with the heel can be formed without additional processing.

Figure 7 is an exploded perspective view showing the form of combining the zip and the band of the subject innovation to form a midsole constituting an embodiment of the subject innovation.

The midsole of the present invention does not have a metal shank part to prevent deformation therein, and the subband 10 protrudes downward on the bottom and extends in the longitudinal direction. ) If the sole or the tack 20 does not have a structure for accommodating the shank portion, the shoe sole is lifted in this portion, the coupling force between the components forming the shoe sole is bad, and the user's balance, stability is deteriorated. Therefore, here, the perforations 21 are formed in the region of the tack 20 corresponding to the sub-shank 11 indicated by the dotted line. Therefore, as shown in the drawing, the shank portion 11 is inserted into the perforation portion 21, and when the adhesive 71 is applied to the upper and lower surfaces of the tack at the other contacting portion and adheres closely, the entire midsole has no large step. It becomes a face.

Figure 8 is a partially cut perspective view showing an embodiment of women's shoes formed by applying the midsole constituting an embodiment of the present invention, Figure 9 is a partially enlarged view showing a laminated structure of the cut portion.

The women's shoes of the present invention mainly target women's shoes having a sole 40 and a midsole, which includes a heel 50 as the flooring material, preferably 5 cm or more. In the case of an adult foot of 5 cm or more, the inclination of the sole of the shoe, the pathology of the high heels, and the feeling of use are relatively strong.

Also in this embodiment, the sole 40 and the midsole are used as the sole (bottom), the upper 30 is interposed between the sole 40 and the midsole in the periphery. Upper 30 is first coupled with the midsole, in this state is coupled with the sole 40, where the midsole is formed only of the tack 20 in the upper 30 and the portion of the tack 20 overlaps with the upper and the tack Fix using a fixture 73 penetrating together. Of course, the adhesive 71 may be further used in this part. In such a case, the upper portion and the midsole 10 may be formed by fixing the upper and the midsole only with the adhesive 71 at the portion where the band 10 overlaps with the traction 20. This is because it may be difficult to install a fixture for fixing the midsole and the upper 30 to each other in a state in which the hole for the fixture 73 is not drilled in the belt. Here, the fastener may be any of a variety of existing fasteners such as pins, nails, bolts, stapler cores.

On the other hand, in a sandal-type shoe where the upper portion of the upper portion is mainly concentrated on the front part of the foot, it is not necessary to use a fastener for coupling the upper 30 with the lower portion 10, and the middle portion of the upper portion 10 overlaps with the midsole. When combining the midsole and the upper 30 in the form of a string only in a portion of the can be formed in advance in the manufacturing step, such as molding holes for joining the fasteners to the band.

In addition to the band and midsole of the present invention, a conventional paper band may be applied. In order to maintain the feature line (S) feature of the present invention with respect to the paper material of the present invention, several methods can be used. First, when forming the shank portion of the shank portion while forming the longer shape of the shank portion to prevent deformation while maintaining the strength of the umbilical cord, the overall shape of the entire umbilical cord including the metal shank portion is adjusted by adjusting the curved shape in the longitudinal direction of the shank portion. Creating feature line features.

Next, since the paper material band is made by stacking a plurality of thin paper layers, an adhesive for bonding these layers is used. Although it is difficult to form the shape of each paper layer by a frame like a feature line feature, it is difficult to form the shape of the paper layer in a stacked state before the drying of the adhesive material is completely done while adjusting the characteristics through the solvent of the adhesive material to bond the paper layers. The whole form of the paper band can be adjusted to have the characteristics of the shape line of the present invention while applying heat and pressure or applying moisture. The above two methods can be used separately or together.

Although the present invention has been described in detail only with respect to the specific embodiments described, it will be apparent to those skilled in the art that various modifications and changes are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended utility model registration claims. It is natural.
